An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-46760 and fix it if it is affected.\n\nWhat it is: CVE-2021-46760 is a critical memory corruption vulnerability in 3rd Gen AMD Ryzen™ Threadripper™ Processors “Castle Peak” HEDT, published on 9 May 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-46760 in the wild and no public exploit code.\n\nAffected product: 3rd Gen AMD Ryzen™ Threadripper™ Processors “Castle Peak” HEDT. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-46760/ (Markdown: https://insights.sbomify.com/CVE-2021-46760/index.md)","id":"CVE-2021-46760","markdown":"https://insights.sbomify.com/CVE-2021-46760/index.md","name":"CVE-2021-46760","record":{"aliases":["GHSA-qh8v-25c7-7m9h"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"AMD Ryzen Threadripper","requires_auth":"none","summary":"A malicious application can trigger an out-of-bounds memory access in the bootloader, potentially leaking sensitive information or executing code on AMD Threadripper systems.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[{"product":"ryzen_3945wx_firmware","vendor":"amd"},{"product":"ryzen_3955wx_firmware","vendor":"amd"},{"product":"ryzen_3960x_firmware","vendor":"amd"},{"product":"ryzen_3970x_firmware","vendor":"amd"},{"product":"ryzen_3975wx_firmware","vendor":"amd"},{"product":"ryzen_3990x_firmware","vendor":"amd"},{"product":"ryzen_3995wx_firmware","vendor":"amd"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A malicious or compromised UApp or ABL can send\na malformed system call to the bootloader, which may result in an out-of-bounds\nmemory access that may potentially lead to an attacker leaking sensitive\ninformation or achieving code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in 3rd Gen AMD Ryzen™ Threadripper™ Processors “Castle Peak” HEDT","id":"CVE-2021-46760","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2021-46761"},"packages":[],"prev":{"headline":"Memory corruption in Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics “Pollock”","id":"CVE-2021-46759"},"products":["3rd Gen AMD Ryzen™ Threadripper™ Processors “Castle Peak” HEDT","Ryzen™ Threadripper™ PRO Processors “Castle Peak” WS"],"published":"2023-05-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-01-27","vendors":["AMD"]},"summary":"A malicious application can trigger an out-of-bounds memory access in the bootloader, potentially leaking sensitive information or executing code on AMD Threadripper systems.","url":"https://insights.sbomify.com/CVE-2021-46760/"}
